2. Introduction
2.1 Safety warning
2.1.1 Read this booklet
This booklet is designed to help a certified
installer install, begin operation of and trouble-
shoot the Grundfos UPS pumps. The booklet
should be left with the owner of the pump for
future reference and information regarding its
operation. Should the owner experience any
problems with the pump, a certified professional
should be contacted.
2.1.2 Electrical work
3. Pre-installation checklist
3.1 Confirm you have the correct pump
• Read the pump nameplate to make sure it is
the one you ordered.
• Compare the pump's nameplate data and its
performance curve (for head, gpm, etc.) with
the application in which you plan to install it.
• Will the pump do what you expect it to do?
3.2 Check the condition of the pump
The shipping carton your pump came in is
specially designed around your pump during
production to prevent damage.
As a precaution, it should remain in the carton
until you are ready to install it. At that point, look
at the pump and examine it for any damage that
may have occurred during shipping.
Examine any other parts of the shipment as well
for any visible damage.
3.3 Verify electrical requirements
Verification of the electrical supply should be
made to be certain the voltage, phase and
frequency match that of the pump motor. The
proper operating voltage and other electrical
information can be found on the pump
nameplate.
These motors are designed to run on + / - 10 %
of the nameplate-rated voltage.
Wiring connection diagrams can be found inside
the terminal box cover and later in these
Installation and Operating Instructions. If voltage
variations are larger than + / - 10 %, do not
operate the pump.
Warning
All electrical work should be
performed by a qualified
electrician in accordance with the
latest edition of the National
Electrical Code, local codes and
regulations.
Warning
A faulty motor or wiring can cause
electrical shock that could be fatal,
whether touched directly or
conducted through standing water.
For this reason, proper grounding
of the pump to the power supply's
grounding terminal is required for
safe installation and operation.
In all installations, the above-
ground metal plumbing should be
connected to the power supply
ground as described in Article
250-80 of the National Electrical
Code.

3.4 Pumped liquid requirements
CAUTION: The UPS pump is intended for use
with water only.
The pump can be used to circulate:
• Potable hot water
• Water for hydronic heating
• Cooling water
• In domestic hot-water systems it is advisable
to use bronze pumps (UPS model) only for
water with a degree of hardness lower than
14 grains per gallon of hardness. For water
with a higher degree of hardness, a
direct-coupled Grundfos TP pump is
recommended.
• If the pump is installed in a heating system,
the water should meet the requirements of
accepted standards on water quality in
heating systems.
The pump is lubricated and cooled by the liquid
being pumped. Therefore, the pumped liquid
must always be allowed to circulate through the
pump. Extended periods without circulation will
cause premature wear to the bearings and
excessive motor heat. The pumped liquid must
also meet the following requirements:

4. Installation procedures
4.1 Electrical preparation
Terminal box position
At the bottom of the stator, closest to the pump
housing, there are eight drain holes to allow
condensed water to escape. The drain holes
shall not be blocked. The drain holes must point
downwards. The terminal box must therefore
point upwards in one of the positions shown in
fig. 1. The following terminal box positions apply
whether the piping is mounted vertically or
horizontally.
Fig. 1 Possible terminal box positions
Rotating the terminal box
To change the position of the terminal box,
follow these steps:
1. Remove the four allen-head screws holding
the pump head onto the pump housing.
2. Carefully lift the pump head and rotate it so
the terminal box is in the desired position.
DO NOT locate the terminal box beneath the
pump. Make sure the O-ring is properly
seated in the pump housing.
3. Replace the pump head onto the pump
housing.
4. Tighten the allen-head screws evenly.
Torque to:
8 mm............15 ft lbs
10 mm..........25 ft lbs.
5. Check to make sure the rotor turns freely. Do
this by removing the vent plug in the middle
of the pump nameplate. Insert a medium size
flat-blade screwdriver into the slot at the
exposed end of the shaft. Gently turn the
shaft. If it does not turn easily, repeat steps 1
to 4 above.
6. The position of the nameplate can be
changed by easing the outer edge of the
plate at the cutout with a screwdriver. Turn
the nameplate to the required position and
push into place.
7. Refer to p. 17 and p. 18 for additional
instructions.
4.2 Piping considerations
Thoroughly clean and flush all dirt and sediment
from the system before attempting to install the
pump.
Location in the piping line
The pump should never be located at the lowest
point of the piping system, where dirt and
sediment collect. Nor should it be located at the
highest point of the piping system, where air
accumulates.
Mounting positions
The arrows on the flanges of the pump indicate
the direction of water flow. Although the UPS
may be installed in either vertical or horizontal
piping, the motor shaft must always remain
horizontal, as shown in fig. 1 and fig. 2.
Fig. 2 Direction of water flow through the
pump
NOTE: Pumps installed outdoors must be
protected by a ventilated, watertight cover to
keep out moisture and dirt.
Warning
Never make any connections in the
pump terminal box unless the
electrical supply has been switched
off.
TM03 7296 4706
Warning
If the pump is already installed in
the system, the system must be
drained or the isolation valves on
both sides of the pump must be
closed before the allen-head
screws are removed as the pumped
liquid may be scalding hot and/or
under pressure.
Do not start the pump until the
system has been filled with liquid
and vented.
TM03 7290 4706
Warning
The pump must be positioned so
that someone cannot accidentally
come into contact with the hot
surfaces of the pump.
6
(QJOLVK86
4.3 Connect the pump
Install the pump into the piping system.
Grundfos recommends that pressure gauges be
installed in the inlet and discharge flanges or
pipes to check pump and system performance.
4.4 Electrical connection
The electrical connection and protection should
be carried out in accordance with the latest
edition of the National Electrical Code, local
codes and regulations by a qualified electrician.
The operating voltage and frequency are
marked on the pump nameplate. Make sure that
the motor is suitable for the electrical supply it is
being installed to.
The pump should be grounded to protect against
indirect contact and a ground fault interrupter
can be used as extra protection.
Multi-speed pump (single-phase)
All single-phase pumps are equipped with
built-in, automatic resetting, thermal overload
protection. The pump is protected at all three
speeds.
Multi-speed pump (three-phase)
The pump must be connected to the electrical
supply via an external contactor. The contactor
must be connected to the built-in thermal
overload switch terminals T1 and T2 (3 x
208-230 V) or P1 and P2 (3 x 460 V and 575 V)
to protect the pump against overloading at all
three speeds.
OR: If the pump is protected by means of a
motor starter, the starter must be set to the
current consumption of the pump at the selected
speed. The motor starter setting must be
changed every time the pump speed is changed.
The current consumption at the individual
speeds is stated on the pump
nameplate.
Figures 4, 6, 7, 9, and 10 on the next pages
show the possible connections.

5. Starting the pump
5.1 Vent the piping system
After the pump has been installed and the
electrical connections made, the piping system
must be vented.
CAUTION: Never operate the pump dry — the
system must first be filled with liquid and vented.
NOTE: Do not vent the piping system through
the pump.
Instead, follow these steps:
1. Fill and pressurize the system with liquid,
and vent all trapped air from the piping by
suitable means.
2. If any isolation valves are used, make sure
they are OPEN.
5.2 Check the direction of shaft rotation
Applies to 460 V and 575 V two-speed models
only
(The direction of rotation of three-speed pumps
is checked by means of the fault finding chart,
p. 10 and p. 11).
1. Make sure that the power is OFF.
2. Unscrew and remove the vent plug located
at the center of the nameplate.
3. Insert a small, flat-blade screwdriver into the
slot in the end of the motor shaft (see fig.
12). Rotate the shaft with the screwdriver to
make sure it does so freely.
4. Bump the pump and watch to see which
direction the shaft rotates. The shaft must
rotate in the counterclockwise direction as
shown on the nameplate (see fig. 11).
5. If the pump shaft is rotating incorrectly,
disconnect the power and interchange any
two power leads in the terminal box.
6. Check once again for proper counterclock-
wise rotation. When it is rotating correctly,
replace the vent plug.

6.2 Preliminary checks
Supply voltage
To check the voltage being supplied to the
motor, use a voltmeter.
Fig. 17 Checking single-phase power
Evaluation
When the motor is under load, the voltage
should be within 10 % (+ or –) of the nameplate
voltage. Any variation larger than this may
indicate a poor electrical supply and can cause
damage to the motor windings. The motor
should not be operated under these conditions.
Contact your power supplier to correct the
problem or change the motor to one requiring
the voltage you are receiving.
7. Single-phase
pumps with
protection
module (only).
The pump does
not run.
The red
indicator light is
on.
The green indi-
cator light is off.
a) The pump has been cut
out by the thermal over-
load switch due to high liq-
uid temperature or blocked
rotor.
Check that the liquid temperature falls
within the specified range. The pump will
restart automatically when it has cooled to
normal temperature.
NOTE: If the thermal overload switch has
cut out the pump three times within a short
period, the pump must be restarted
manually by switching off the electrical
supply.
b) The speed switch module
has not been fitted.
Switch off the electrical supply by means
of the external mains switch and fit the

6.3 Current measurement
To check the current, use an ammeter.
To do so, follow these steps:
1. Make sure the pump is operating.
2. Set the ammeter to the proper scale.
3. Place the tongs of the ammeter around the
leg to be measured.
4. Compare the results with the amp draw
information on the motor nameplate.
5. Repeat for the other legs.
Evaluation
If the current draw exceeds the listed nameplate
amps, or if the current imbalance is greater than
5% between each leg on three-phase units, then
check the following:
• The voltage supplied to the pump may be too
high or too low.

(lead-to-ground) of the motor and leads, a
megohmmeter is required.
To do so, follow these steps:
1. Turn the POWER OFF.
2. Disconnect all electrical leads to the motor.
3. Set the scale selector on the megohmmeter
to R x 100K, touch its leads together, and
adjust the indicator to zero.
4. Touch the leads of the megohmmeter
individually to each of the motor leads and to
ground (i.e. L1 to ground; L2 to ground, etc.).

2. Introduction
2.1 Vertissements de sécurité
2.1.1 Lisez ce manuel
Ce manuel est destiné à aider l'installateur
certifié à installer, faire fonctionner et réparer la
pompe Grundfos UPS. Le manuel devrait être
laissé au propriétaire de la pompe pour
référence future. Si la pompe présente des
problèmes, communiquez avec un professionnel
certifié.
2.1.2 Travaux électriques
3. Liste de vérification pour
la préinstallation
3.1 Assurez-vous d'avoir la bonne
pompe
• Lisez la plaque signalétique de la pompe
pour vérifier qu'il s'agit bien de celle que
vous avez commandée.
• Comparez les données de la plaque
signalétique et la courbe de rendement de la
pompe (débit, hauteur d'aspiration, gal/min.,
etc.) avec les demandes qu'elle devra
rencontrer.
• Assurez-vous que la pompe puisse répondre
à vos besoins.
3.2 Vérifiez l'état de la pompe
Le carton dans lequel vous avez reçu votre
pompe est spécialement conçu pour épouser la
forme de celle-ci. Il est disposé autour d'elle en
cours de production afin de prévenir les
dommages.
En guise de précaution, laissez la pompe dans
le carton jusqu'à son installation. À ce moment,
examinez la pompe pour tout dommage qu'elle
aurait pu subir au cours du transport.
Examinez également toute autre pièce pour
vérifier s'il y a bris.
3.3 Vérifiez les exigences électriques
La vérification de la source d'alimentation doit
être effectuée pour s'assurer que la tension, la
phase et la fréquence correspondent à celles du
moteur de la pompe. Ces données sont
indiquées sur la plaque signalétique de la
pompe.
Le moteur est conçu pour fonctionner à une
tension située à + / - 10 % de la tension énoncée
sur la plaque signalétique.
Les schémas de câblage se trouvent à l'intérieur
du couvercle du boîtier de raccordement, et plus
loin dans ce manuel. Si les variations de la
tension sont supérieures à + / - 10 %, ne faites
pas fonctionner la pompe.
Advertissement!
Tout travail électrique doit être
effectué par un électricien qualifié
en vertu de la dernière édition du
National Electrical Code (É.-U.) ou
du Code national de l'électricité
(Canada) en plus des codes et des
règlements locaux.
Advertissement!
Un moteur ou des câbles
défectueux peuvent entraîner des
chocs électriques pouvant être
fatals lorsque touchés directement
ou mis en contact avec de l'eau.
C'est pourquoi une mise à la terre
efficace de la pompe sur la borne
de la source d'alimentation est
nécessaire pour assurer une
installation et une utilisation sans
danger.
Dans toutes les installations, les
pièces de plomberie en métal
situées au-dessus du sol doivent
être raccordées à la mise à la terre
de la source d'alimentation tel que
précisé dans l'article 250-80 du
National Electrical Code (É.-U.) ou
dans le règlement 10-406 du Code
national de l'électricité (Canada).
